The much-anticipated flagship from Sony becomes the world’s first smartphone to feature a 4K-resolution display and 23-megapixel rear camera.

The Sony Xperia Z5 Premium features a 5.5-inch TRILUMINOS display with Sony’s X-Reality engine on an IPS panel, with 4K resolution. Display response time on the Sony Xperia Z5 Premium is improved by Sony’s ‘Memory on Display’ technology, which enables it to remember the images that are once incident on the screen, thereby loading them faster in the next reload. The smartphone is powered by Qualcomm’s Snapdragon 810 SoC, and has 32GB of internal storage (expandable up to 200GB via microSD cards). The Xperia Z5 Premium can also upscale video content to 4K, and houses a 3430mAh battery. The camera has a 1/2.3-inch 23-megapixel Exmor RS image sensor, teamed with a Sony f/2.0 Sony G lens. Sony has claimed a hybrid autofocus response time of 0.03s in the “first completely reimagined smartphone camera module”, which also features Sony’s SteadyShot image stabilisation and Intelligent Active Mode for videos. Sony’s LDAC codec for wireless transmission claims three times more efficient data transfer over its previous versions, which should improve bluetooth audio capabilities. The smartphone also has Ingress Progression waterproofing rating of IP65/IP68. A DSEE HX audio chipset is included to provide high fidelity audio. It also comes with Qualcomm’s Quick Charge 2.0 capabilities.
